One-pot facile fabrication of carbon-coated Bi2S3 nanomeshes with efficient Li-storage capability

Design and tailoring of three-dimensional graphene–Vulcan carbon–Bi2S3 ternary nanostructures for high-performance lithium-ion-battery anodes

“…One of most effective ways is to use carbonaceous materials that can act as a buffer matrix against volume expansion during cycling and as a conductive substrate. 13,14 Recently, graphene, a two-dimensional carbon material with sp 2 bonding, has been considered as a new matrix material to improve electrochemical performance of bismuth suldes. For example, Zhang et al synthesized Bi 2 S 3 @graphene nanocomposites by a hydrothermal method and reported that the Bi 2 S 3 @graphene electrodes exhibit a high capacity of 400.5 mA h g À1 aer 50 cycles at a current density of 100 mA g À1 with 95% capacity retention.…”

Carbon coated flower like Bi 2 S 3 grown on nickel foam as binder-free electrodes for electrochemical hydrogen and Li-ion storage capacities

“…The capacity loss between discharge and charge process may be attributed to the formation of SEI layer and the formation of conversion product of Li 2 S and alloying product of Li 3 Bi. [18,26] During the 2nd cycle, the electrode presents a discharge capacity of 840 mAh g À1 and a corresponding charge capacity of 737 mAh g À1 , resulting in the Coulombic efficiency of 87.7%. This value can be retained as 94% even after 50 cycles.…”

“…For example, carboncoated Bi 2 S 3 nanomeshes with large capacity and stable cyclability have been fabricated. [18] Ni's research group reported that bismuth sulfide-carbon nanotube hybrid exhibited a high reversible capacity and remarkable rate capability. [19,20] These Bi 2 S 3 / carbon hybrids could enhance electronic conductivity and provide flexible space for suppressing the large volume expansion during cycling.…”

Facile Synthesis of Bi2S3@SiO2Core-Shell Microwires as High-Performance Anode Materials for Lithium-Ion Batteries

“…14,15 Due to its lamellar structure, Bi 2 S 3 is also investigated as an ideal host for hydrogen 16,17 and lithium storage. 18,19 As an anode material for LIBs, Bi 2 S 3 can afford the theoretical capacities of 625 mA h g −1 by mass and 4250 mA h cm −3 by volume, which is much higher than that of graphite. Although Bi 2 S 3 has many advantages, such as high capacity, nontoxic, and low cost, its practical application is hindered by the poor cycling stability due to its large volumetric expansion.…”

“…Combining active materials with carbonaceous matrix is another way to accommodate the volume expansion during charge-discharge process. 19,26,29 Ni et al synthesized Bi 2 S 3 @CNT composite, which shows excellent electrochemical performance. It delivers a capacity of 405 mA h g −1 at 1 A g −1 after 100 cycles.…”
